7Check Digit Verification of cas no
The CAS Registry Mumber 12769-07-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,7,6 and 9 respectively; the second part has 2 digits, 0 and 7 respectively.Calculate Digit Verification of CAS Registry Number 12769-07:
(7*1)+(6*2)+(5*7)+(4*6)+(3*9)+(2*0)+(1*7)=112
112 % 10 = 2
So 12769-07-2 is a valid CAS Registry Number.
